Yes I have I recently took dark cyde sledge. Started of taking one dose a day then after my first week of taking it I added it up to two pills a day one in the morning and one at night. I did drink plenty of water and ate around 2800 calories a day. I was using jacked for a pre supplement and gold standard whey after the workout everyday and one at night. At the moment I weight 145lb and with a percentage of 10 percent body fat and 5"5.
